8.2 Explanation of Registers

REG00 (local station address)
This register can set own wireless address. When the FDP03 receives a packet that destination is this
address, the FDP03 processes the packet. The setting range is 00H to EFH (000 to 239). If the value is
set to invalid range, the FDP03 returns N0 response.
REG01 (group address)
This is the wireless group address of the FDP03. When the FDP03 receives a packet that group is this
address, the FDP03 processes the packet.
If "Enabling destination address check at reception" function of the REG18 is turned on, the FDP03 returns
ACK signal to sender FDP03 when it receives a packet. Therefore, if "Enabling destination address check
at reception" function of all FDP03 in the system is turned on, all FDP03 that receive a packet return ACK
signal. Thus, to avoid unnecessary communication, the REG18 may be set to "Disabling destination
address check at reception".
The range of the setting value is F0H to FEH (240 to 254). If the value is set to invalid range, the FDP03
returns N0 response.
REG02 (headerless-packet destination address) (only for the headerless packet transmission mode)
This register indicates the destination address of packet data in headerless packet transmission mode. This
register also indicates the wireless address of the connection destination when TS2 command is used.
The range of the setting value is 00H to FFH (000 to 255). If the value is set to invalid range, the FDP03
returns N0 response.
REG03 (transmission mode)
This register setting can change the transmission mode, which is packet transmission mode or headerless
packet transmission mode.
F0H
FFH
The value of the setting is F0H (packet transmission mode) or FFH (headerless packet transmission mode).
If the value is set to invalid range, the FDP03 returns N0 response.
REG04 (ID code 1)
This register setting defines data scramble ID. Combined with ID code 2 (REG05), variation of data
scramble ID is up to 65,536.
Range of the setting value is 00H to FFH and FDP03 returns N0 response if the value is out of the range.
Packet transmission mode (default)
Headerless packet transmission mode
The same scramble code (REG04 and REG05) must be set on all the
FDP03s in the system. If the scramble codes are different each other,
each FDP03 cannot communicate with.
